Our 5-axis CNC machining service enables the production of complex, high-accuracy components. Tight tolerances up to ±0.01 mm are supported, with online quoting available for custom metal and plastic parts.
5-axis machining is a CNC process in which the cutting tool moves along three linear axes (X, Y, Z) while the workpiece or tool simultaneously rotates on two additional axes. This allows the tool to machine a part from multiple angles in a single setup.
By maintaining optimal tool orientation during cutting, 5-axis machining enables accurate machining of complex geometries, angled features, and contoured surfaces. Fewer setups help reduce positioning errors and improve overall dimensional consistency.
3-axis CNC machining allows cutting along three linear axes (X, Y, and Z) and is suitable for parts with simple geometries, flat surfaces, and basic contours. While it is highly accurate and cost-effective for many applications, complex shapes often require multiple setups, additional fixturing, and manual repositioning, which increases production time and the risk of cumulative errors.
In contrast, 5-axis CNC machining adds two rotary axes, enabling the cutting tool to approach the workpiece from virtually any angle. This allows for the efficient production of intricate geometries, deep cavities, angled features, and contoured surfaces in a single setup. The result is higher precision, reduced setup time, fewer fixture changes, and improved surface finish, making it ideal for aerospace, medical, automotive, and other high-complexity parts.
A wide selection of metals and plastics can be processed using 5-axis CNC machining, enabling accurate machining of complex features across different material types. Choosing the appropriate material helps optimize machining efficiency, part performance, and overall cost. Engineering support is available to assist with material selection when needed.
Surface finishes are applied to enhance part performance, durability, and appearance. We offer a wide range of finishing options compatible with 5-axis CNC machined components to meet functional and application-specific requirements.
| Surface Finish | Description |
|---|---|
| As Machined | Parts are delivered directly after CNC milling, with visible tool marks remaining. Suitable for functional components where surface appearance is not a primary concern. |
| Anodizing | An electrochemical surface treatment primarily used for aluminum parts to enhance corrosion resistance, surface hardness, and color consistency. |
| Polishing | Reduces surface roughness to achieve a smooth, refined finish, improving appearance and reducing friction in functional areas. |
| Sand Blasting | Applies abrasive media to create a uniform matte texture, improving surface consistency or preparing parts for additional coatings. |
| Brushing | Creates a controlled linear texture on visible surfaces, commonly used where a consistent directional finish is required. |
| Powder Coating | Applies a durable protective layer that improves corrosion resistance and provides a wide range of color options. |
| Electroplating | Deposits a thin metal layer to improve corrosion resistance, wear performance, or electrical conductivity. |
| Black Oxide | A chemical conversion coating mainly used on steel parts, providing mild corrosion protection and a uniform black appearance. |
| Passivation | Enhances corrosion resistance of stainless steel parts by removing surface contaminants and free iron from the surface. |
| Heat Treatment | Alters material properties of milled parts to improve hardness, strength, or wear resistance based on application requirements. |
